Ecological Succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

Front

What is a pioneer community in ecological succession?

Back

A pioneer community is the first group of organisms that colonize a barren or disturbed area, initiating the process of ecological succession.

Front

What typically happens to species diversity as ecological succession progresses?

Back

The number of species typically increases as ecological succession progresses.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession, characterized by a complex structure and a stable species composition.

Front

What is primary succession?

Back

Primary succession occurs in an area where no soil exists, such as after a volcanic eruption or glacial retreat, starting from bare rock.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire.

Front

What role do lichens and mosses play in primary succession?

Back

Lichens and mosses are often the first organisms to colonize bare rock in primary succession, helping to create soil by breaking down the rock and accumulating organic matter.

Front

What is the correct order of organisms in primary succession?

Back

The correct order is: Rocks, Lichens & Mosses, Bushes & Shrubs, Trees.

Front

What is the significance of soil in ecological succession?

Back

Soil is crucial for supporting plant life; its development is a key factor in the progression from pioneer species to a climax community.

Front

How does disturbance affect ecological succession?

Back

Disturbance can reset the succession process, leading to secondary succession, which can alter the trajectory and speed of community recovery.
